Portal Hypertension: Introduction - Hopkins Medicine
www.hopkinsmedicine.orgthan 5 mm Hg greater than the inferior vena cava pressure is defined as portal hypertension. Clinically it may be difficult to detect portal hypertension until pressures are much higher. There are many causes of portal hypertension including etiologies above the liver, within the liver, and below the liver. Suprahepatic Causes
